Description
Technical Field
The present invention relates to the field of distributed operating systems, and more particularly, to a method, system, device, and storage medium for process collaboration in a cluster.
Background
Operating systems currently run on a separate host. Management is performed for the current host operating system process. The independent host can uniformly manage different processes according to the process state of the current operating system and the system resource condition. In the process of scheduling, the process mainly performs uniform resource allocation for the process of the local machine, and allocates process resources of different CPUs. The scheduling of the process is also based on the scheduling of the physical architecture for uniform resource allocation. When the resources of the system are exhausted, the operating system selects a process consuming a large amount of system resources to kill the process in order to ensure that the operating system can operate and work normally. Therefore, under the premise of limited resources, the single operating system cannot allocate and schedule resources any more and can only select to kill part of processes under the condition of resource exhaustion.
Therefore, in response to the above problems, there are many different solutions within the industry, such as: the method mainly adopts the implementation scheme that the whole application is evaluated, the peak performance consumption of the service is calculated, the whole evaluation is carried out on the application and the framework of the operating system after the calculation is finished, the application is guaranteed not to be killed in the peak time, the normal operation can be carried out, and once the application exceeds the evaluation value of the evaluation, the whole application still has the possibility of being killed.
The main existing solution is an operating system high availability scheme, that is, a plurality of operating systems form an operating system cluster, the operating system cluster is configured as a high availability cluster, the operating mode is a host elected inside the plurality of operating systems, the host is responsible for coordinating the operating mode inside the whole cluster, and first, the hosts communicate with each other by using a heartbeat mechanism, so as to ensure that whether each host monitors each other to survive. Once a certain host is offline or down, the host which cannot normally work is offline. And simultaneously, the host transfers the service operated by the offline server to a new host for operation. The resources among the servers are mainly: 1. file sharing: adopting NFS file system format, based on network file system; 2. computer network resources: and a plurality of Linux hosts mutually interact in the local subnet together. Thus, in the above manner, the availability of the entire cluster is ensured.
Through the technology, elections are carried out by the hosts in the whole cluster, and the hosts have absolute control rights. Therefore, the following problems arise: 1. if the host fails. The election will be made by the other machine. If other machines cannot communicate with each other due to host failure at this time, a "split" situation occurs, i.e., one host stops, forming a plurality of clusters, each cluster having one host, but normally, the remaining servers should elect a new host. Once this happens, the whole cluster will be down; 2. if a host fails due to overhigh load, a new host can take over the tasks of the original host with overhigh load, the load of the new host can be suddenly increased, and the probability can also fail, so that the tasks are migrated to a third host, and the failure of the hosts one by one can cause the failure of the whole cluster, which is generally called as an avalanche problem; 3. relying too much on the heartbeat mechanism, which can only ensure that the host is still alive, but cannot ensure that the service is still working properly, for example: if a process is deadlocked, the server can still work normally, but the process cannot work normally, and although the whole cluster still lives, the service is stopped, and the process is completely out of order.

Detailed Description
In order to make the objects, technical solutions and advantages of the present invention more apparent, the following embodiments of the present invention are described in further detail with reference to the accompanying drawings.
It should be noted that all expressions using "first" and "second" in the embodiments of the present invention are used for distinguishing two entities with the same name but different names or different parameters, and it should be noted that "first" and "second" are merely for convenience of description and should not be construed as limitations of the embodiments of the present invention, and they are not described in any more detail in the following embodiments.
In a first aspect of the embodiments of the present invention, an embodiment of a method for process cooperation in a cluster is provided. Fig. 1 is a schematic diagram illustrating an embodiment of a method for process cooperation in a cluster according to the present invention. As shown in fig. 1, the embodiment of the present invention includes the following steps:
s1, configuring all hosts to the same network segment, establishing communication between each host and other hosts, and monitoring resource configuration condition of each host;
s2, responding to the fact that the resource configuration of the first host exceeds a threshold value, calculating the resource consumption of each process in the first host, and determining the process with the maximum resource consumption;
s3, initiating a migration broadcast to the cluster, and judging whether a second host computer exists in the cluster to respond to the broadcast;
s4, responding to the broadcast of the second host existing in the cluster, and sending the process with the maximum resource consumption to the second host; and
and S5, configuring the cluster working mode into three working modes of dynamic detection, a fixed host list and a main/standby host list.
All the hosts are configured in the same network segment, the communication between each host and other hosts is established, and the resource configuration condition of each host is monitored.
All the hosts are configured into a cluster by building a local area network. The network segments of the hosts can be configured to be the same local area network, for example, after the cluster is configured to 192.168.11.0/24 network segments, the hosts configured to the network segments are all cluster hosts. The hosts can ping each other. Configure by modifying the configuration/etc/rpcha. The configuration contents include: cluster network segment address, cluster working mode and cluster resource allocation threshold. The cluster network segment address configuration mode is network segment address + subnet mask; the cluster working mode can be configured into three working modes of dynamic detection/fixed host list/main/standby host list; the resource configuration threshold of the cluster is the lowest resource configuration value of the operating system for process migration.
The servers are configured in the same network segment, and the clusters are defined in a network segment mode, so that the hosts in the network segment can communicate with each other. And simultaneously, main and auxiliary machines are not designated, the status of each machine is equal, and all hosts in the network segment are the machines of the cluster.
In the context of the present application, the network IP is externally consistent: after configuration is completed, an out-of-cluster IP may be configured. The IP address points to the cluster. The host of a particular cluster response is determined internally by the cluster. For example, an IP points to an a host in cluster ABC, which IP may point to other hosts immediately after host a goes down. Therefore, the appearance is consistent, and all the IP accesses are normal. The user can not sense that the switching of the host computer is generated inside in the using process, and the user satisfaction degree is improved. Further, the IP may be organized in the form of a floating IP.
There are three cluster operating modes, and each operating mode determines the interaction mode of the servers in the cluster. The three working modes are respectively as follows:
dynamic monitoring: dynamic detection is the dynamic discovery of hosts within a clustered network. Because only the hosts configured in the network segment are regarded as nodes in the cluster, the main implementation scheme of dynamic detection is that each time a new host joins the cluster, the new host initiates broadcasting into the local area network. The broadcast content is the address of the new host, and the name of the new host. And after receiving the broadcast message sent by the new host in other existing clusters, automatically recording the basic information of the new host node. For example, there are 10 hosts in the current cluster, and when a host node needs to be added to the cluster, only the server needs to be configured into the corresponding network, and after configuration is completed, the server is added to the cluster through an initialization command (rpcha-init) of the cluster. The command initiates a local area network to broadcast and inform other clusters, each host records ip and name information of a newly added node, and the clusters become 11 hosts.
List of fixed hosts: fixed host lists are the reverse of dynamic detection. The fixed host list cannot dynamically configure the host nodes, and only some nodes can be fixedly configured as host list nodes. If the host node needs to be changed, such as online or offline, the configuration file needs to be modified uniformly. The configuration mode is relatively fixed in operation, cannot dynamically increase or decrease the host, but has stronger control granularity. The method is suitable for a relatively clear and stable host cluster scene.
List of master and slave hosts: the above two configurations are combined. The working mode of the main and standby host computer lists is a mechanism combining main and standby operation. The host computer adopts a basic configuration mode, the standby computer adopts a dynamic increasing mode, for example, a certain cluster adopts 5 servers as the host computer to work, and the general condition can be met. The standby machines are in the same network segment but are not configured in the host list, so the standby machines adopt a dynamic increasing mode. When a new host needs to be added to the server, the server is firstly configured into the network segment and then initialized by using an initialization command in accordance with the dynamic detection scheme.
In some embodiments, the monitoring the resource configuration of each host includes: acquiring the CPU utilization rate, the memory utilization rate and the file system utilization rate of the host, carrying out weighted calculation according to the preset CPU utilization rate weight, the preset memory utilization rate weight and the preset file system utilization rate weight to obtain the resource configuration of the host, and comparing the resource configuration with the threshold.
When the resource allocation of a host reaches a threshold, new processes cannot be executed continuously. The threshold is configured as a percentage, e.g., 80% configured as 80. The threshold value of the resource allocation is calculated by adopting a weighted calculation weight value mode. It is possible, for example: the CPU utilization weight is 5, the memory utilization weight is 3, the file system utilization weight is 2, the CPU utilization is 100%, the memory utilization is 60%, and the file system utilization is 90%, the weight (5 × 100+3 × 60+2 × 90)/10 =86 is calculated. At this time, process migration is required. The most computationally expensive process may continue to be computed using the algorithm. The weighted consumption of each process is calculated. And selecting the highest process for process migration.
In response to the existence of a process having a resource configuration of the first host that exceeds a threshold, calculating a resource consumption amount of each process in the first host, and determining a process having a maximum resource consumption amount.
And initiating a migration broadcast to the cluster, and judging whether a second host exists in the cluster or not to respond to the broadcast. And after processes needing migration are elected, broadcasting is initiated into the cluster, and if the server receiving the broadcasting can process new processes, the broadcasting is responded.
And responding to the broadcast of the second host in the cluster, and sending the process with the maximum resource consumption to the second host.
In some embodiments, the sending the process with the largest resource consumption amount to the second host includes: and responding to the broadcast responded by a plurality of second hosts, acquiring the current resource utilization rate of each second host, and sending the process with the maximum resource consumption to the second host with the lowest current resource utilization rate.
In some embodiments, the sending the process with the largest resource consumption amount to the second host includes: and suspending the process with the maximum resource consumption, compressing the memory state of the process, and sending the compressed process memory mirror image and the process executable file to the second host. After receiving the response, the host initiating the broadcast suspends the process, compresses the memory state, sends the compressed process memory mirror image and the process executable file to the new host in a mode of copying the cluster local area network file, and the new host continues to run the process.
In some embodiments, the method further comprises: in response to no second host in the cluster responding to the broadcast, limiting resource usage by a process in the first host having a greatest resource consumption. If no host is capable of running the process. Then the resource limit strategy (cgroup) is used to limit the resource usage of the current process. The CPU utilization and the memory file system utilization are limited, and a warning is given to a user. And warning that the cluster resources are currently in a low-speed running state, and waiting for human intervention to modify the cluster resources or uniformly configure the processes.
In some embodiments, the method further comprises: and setting a standby host in the cluster, configuring the host which is currently used into a host list, and setting the standby host into a dynamic increasing mode.
In some embodiments, the method further comprises: and responding to the broadcast that no second host exists in the cluster, and sending the process with the maximum resource consumption to the standby host for execution.
The invention considers the whole operating system cluster as a whole and does not need to elect a host or distribute tasks by the host. Each operating system, by default, runs on its own physical device while performing tasks. Only when a certain condition is reached, the server can select the process which cannot be continuously executed by the local machine to pause, stop the current state of the process and give the current state to other servers with resources to execute the task; in order to ensure that the process can be continuously executed, if all other hosts can not run the process, a sandbox mechanism is started, and the local machine continuously runs the process, but the resource access amount of the process is limited through a resource limitation scheme (cgroup) of an operating system, and an early warning is sent to a server manager to warn that the server is in a limited state and the host needs to be added for running, so that the problem that the server cannot generate avalanche is solved, and the server can be ensured to run at least without being crashed by using a resource access limiting mode; the invention adopts the broadcasting mode for interaction, does not depend on the heartbeat mechanism, and the reason for using the broadcasting mode for interaction is that the heartbeat mechanism needs to establish permanent connection and needs to interact more frequently, while the broadcasting mode is infrequent, communication is not needed under normal conditions, when interaction is needed, the operating systems respond to each other, the interaction frequency is reduced, and interaction is carried out only when necessary.
It should be particularly noted that, the steps in the embodiments of the method for process cooperation in a cluster described above may be mutually intersected, replaced, added, or deleted, and therefore, these methods for process cooperation in a cluster transformed by reasonable permutation and combination shall also belong to the scope of the present invention, and shall not limit the scope of the present invention to the embodiments.
Based on the above object, a second aspect of the embodiments of the present invention provides a system for process cooperation in a cluster.

A virtual subnet may be configured to configure servers within a cluster in the same network segment. After configuration is completed, a server in the cluster is found at any time, and initialization is performed using the operating system command tool rpc _ tools — init. The command tool first reads the configuration via the configuration device. And after the reading is finished, broadcasting is initiated to the cluster through the cluster synchronization device. The machines receiving the broadcast respond to the initialization operation and all initialize local configuration through the local configuration device. And after the initialization of each server is completed, the broadcast is initiated through the server synchronization device. And finally, completing the complete configuration.
After configuration is complete, the process may be initiated at the server cluster. And selecting a server to log in. The process is started using a command line tool. For example to start the demo process. And the process is started in the local computer by default, if the server reaches the configured threshold performance, the process is selected, a process with the largest consumption performance is selected, the broadcast is initiated, and the host computer capable of being hosted is found. After receiving the broadcast, the other servers reply whether the servers can host or not through the synchronization device. A hosting host is selected by the server that originated the hosting broadcast. After the selection is finished, the current process and the server state are compressed through the mirror image compression and backup device and transmitted to the new host, and the process of the local computer is killed. And if the host cannot be found, limiting the resource use of the process in a resource limiting mode and sending out alarm information.
